ADJUSTABLE CORNICE.

Spe'cication of Letters Patent. l Patented lwzty 27, 1919.

Application iiled January 5, 1918. Serial No. 210,466.

cornice especially adapted for mountingI over windows and like places where it may serve, in an ornamental capacity, to conceal rods, cords or other supports for draperies, hangings, etc., and as a support for valance.

Cornices of the kind herein contemplated are frequently mounted over the upper trim surrounding the inner side of a window, and

are usually made to order according to the widths of the windows where they are to be used. The present cornice, however, which is capable of lengthwise adjustment, may be supplied in standard stock lengths and be fitted to the window at the time it is set up in place. In this manner my cornice may be quickly and easily adjusted to conform to any width. of window within the limits of its size, permitting its removal,

if desired, without requiring any special skill or labor in itting it in place. Y

In order that the several par-ts of my cornice may be maintained in rigid relation at all times and 'be possessed with a desirable degree of strength, I have provided several novel and improved features which do not, however, affect measurably the simplicity of its construction, the cost of' its manufacture,` or its ornamental appear- In the drawings: Figure 1 is a perspectiveview ofthe present cornice mounted over an ordinary window. Fig. 2 is a plan viewjof the same. Fig. 3 is a rearview thereof,and Figs. 4 and 5 are enlarged transverse sections taken on lines 4-4f and 5 5 respectively of Fig. 2.

Three major elements constitute the present cornice-a center-piece A and two end sections B and C, each slidingly connected with the center-piece. Arranged in right angular relation with the sections B and C are end pieces 6 and 7, respectively, which serve to space the elements A, B and C out from the window trim or molding 8 to As will bev more fully hereinafterv which the cornice may conveniently be Secured as by means of hook and eye connec-y tions 9.

Each of the sections B and C on its front face is formed with certain ornamental con-` figurations consisting, in part at least, of a plurality of beads or ridges, designated as 10, extending lengthwise of the cornice, a suggested `profile being clearly shown in Figs. 4f and 5. The rear face ofthe centerpiece A is likewise configured to correspond, in a measure at least, with the profile ofthe sections B and C, that is, it is formed with vv grooves or channels 11 having a. complementary relation to the beads or ridges 10. It is obvious, of course, that the presence `of beads or ridges on any of the cornice elements will result in ythe formation of grooves or channels immediately adjacent thereto, and vice versa, so that it will be understood these terms are used in a relative sense.

Upon. the rear face of the center-piece I have arranged in the center thereof a vertical blockl (see Figs. 2, 3 and 5) whose rear side substantially alines with the rear faces of the sections lB and. Cwhen in operative relation with the center-piece. This block, which may be conveniently secured in place with screws v13, .carries a channel bar 14 whose flanges 15 lie within slots 16v y formed in the block, a screw 17 beino employed to fasten the bar upon the block. The facing sides of the bar flanges 15 are preferably obliquely disposed, tapering toward each other in the direction of the bar body. Upon the rear face of each section B and C parallel channels 18 are provided (see Figs. 3 and 4) each having an obliquely inclined side conforming to the slope of the facing sides of the bar flanges 15 and adapted to partly receive therein the said flanges. I prefer also to countersink slightly the surface 19 of the sections'B and C lying between the channels 18, so that .if pressure be brought to bear u on the channel bar, tending. to force its anges farther into -the lchannels 18, the surfaces of the means of the center-piece on the front side and the channel bar on the rear side, these end sections B and C are maintained in straight line relation. The complementar-y beads and grooves formed on the three cornice elements not only assist in .preserving this relat-ion, but prevent these parts tromv reduce the friction ofthe channel barupon Jthe vsections'B and v3C. 'Vhen the proper adjustment has been made, however, the screw should 'be tightened {to ltorce the "bar fflanges A. tightly 'into lthe'channe'ls 18. By so=doing,

the partsof'thecornice Willfbe locked against further 'adjusting movement, and it may thereafterbe handled Without special care.

j The present cornice, it will be noted, is simple in construction and `operation. To lock "the parts in any given position of adjust1nent,it is necessary merely fto tighten a single screw. rfhe pressure exertedbythe bar flanges Within the channels 18 Vresults in forcesbeing appliedilaterally owingtothe oblique relation 'of thek lengaging vvsurfaces, and 4this affords a secure means for fmaintaining Athe parts `in tlieir yproper relation. Owing tothe inter-engagement ofthe coinplelnentaryielements Whichmake upfthe prole ofthe cornice, the several part-sarestectively `secured against sagging of an-y kind.
